NASA's eventual goal is to put astronauts on Mars, but the space agency's Curiosity rover is keeping it busy in the meantime. In a new blog post, NASA said that Curiosity is still exploring the Gale Crater and uncovering the mysteries of the "clay-bearing unit," where it's using its tools to drill into the Martian soil.
While astronauts floating around in the International Space Station (ISS) would have access to exercise machines to counteract these effects, they would have no such equipment on Mars. The gains they'd have from pumping iron at the Gold’s Gym ISS would be gone fast. However, researchers might have found a dietary supplement that can counteract this problem: resveratrol, an antioxidant found in grape skin, blueberries and perhaps most famously, red wine.
